Aim: We prospectively audited adverse events for surgical patients with colorectal cancer who died under surgical care to test the hypothesis that increased critical care and consultant input could be associated with a reduction in adverse events.
Method: Patients with a diagnosis of colorectal cancer who died under surgical care in Scotland from 1996 to 2005 underwent peer review audit using established methodologies through the Scottish Audit of Surgical Mortality.
Results: In the 10-year study period, 3029 patients with colorectal cancer, mean age 76 (13-105) years, died under surgical care, of whom 80% had presented as an emergency admission. Operative intervention was performed in 1557 (51%) patients of whom 1030 (34%) patients had a resection of the cancer. The annual number of patients dying after a cancer resection decreased significantly (P = 0.009). Significant decreases in adverse events were noted over time with a 67% fall in adverse events relating to critical care (P = 0.009), a 37% fall for surgical care (P = 0.04) and a significant increase in consultant anaesthetist and consultant surgeon input, but there was a 9% increase in delay as an adverse event (P = 0.006). The documented anastomotic leakage rate in patients who died increased from 8% in 1996 to 19% in 2005 (P = 0.016).
Conclusion: The number of patients dying with colorectal cancer after surgery has decreased in recent years. Adverse events in these patients have significantly reduced over a decade with increased consultant involvement although there is the potential for further improvement.
